' Be it known that I, Hosen KENNEDY, o

lRose Point/'in the county of Lawrence and State of lnnsylvania, haveinvented a, new

5 and useiiil Improvement in Flexihle- Joint Packiugiswhich improvementis fully set forth in th following,r specification andaccompanylin'gdrawings, in Which-` Figure lisa longitudinal section ofmy imioqnLQved jointpaeking. Fig. 2 is a iiicrspective n view. of thepacking ready for use.

This device has reference to un improvemeent in jointpackings for gesand oil pipes,

`so thatthejoint, instead ofbeing rigid, as here- |5 `tofore, muy bemade exihle, and thus used in cases where the pipes are large and runalong the surface of the ground, around curves,

and over hills and liollows without bursting,

or putting them together in cast-iron collan's.

' 2o A provision of this kind is necessaryin laying.

oil-pipe and natural-gas-pipe lilies. This I aecoinplish by enlarging`the bore of the collar to receive the ends of the pipe.- so as to"introduce a ply of leather; all of which will now be `25 fully setforth in detail. In the accompanying, drawings, A repre sents anordinary oil or gas pipe, and B the collar connecting the joints'. Theusuel male screw, C, and the female screw l) are provided 5o in the endsof the-pi pes, and the collar-B has any ordinary gas or oil pipe, withthe excep- 'tion that the bore of the collar B is made some- -whattergerfthan the ends of the pipe. l'n order tijd@ `the joint may hetight and at the 12 ,"-Same time flexible, I introduce n ply of leather,

E, within this joint, between the seid nulle screw C and female screw D.rlhis leather or packing is made cylindrical or tubular and corrugated,so as to he fitted close upon the screw end C ol'k one pipe and betweenit and the internal screw, l), in the'end ol' the other pipe. ,Y

lt is obvious that, instead of' using; a single ply of leather, a numberof them, as desired or found necessary, may housed; and itis also clearthat, insteadoi' using leather, any other flexible and suitable materialmay he used.

The object and use of this device are quito obvious, as hy ineens of itthe joint may he lnadelcxible, thus permitting the pipe running alongonuneven ground and over hol lows, and at the same time the introductionof the leather dispenscswith soldering or alle ing of thejoints.

Having' described my invcntiilnnwlnlt l claim 1slhe combinzttion of thepipe A, the collar B, the mele screw C, and fein'ale screw D, with thecylindrical or tubular and corrugated packing E, the whole arranged asand for the purpose substantially as herein set forth and described. J

' lu testimony that l claim the foregoing lY have hereunto set my hand,this 20th day ol' January, 1886, in the Ypresence of witnesses.
